Im trying to connect two LEDs to a pic port pin so that one lights
when the output is low, the other lights when the output is high, and they are
both off when the pin is tri-stated as an input. The first two requirements are
easily met in a lot of ways but I cannot figure out a simple way to get both
leds off when the pin is put into a hiZ state.  I am looking for a solution
that uses just a few extra transistors and resistors - not something with
PALs or OpAmps.

        I have spent a bit of time puzzling over this and I am overlooking
something obvious or it is not as simple as it seems.  I think it can be
done using both a p-channel and n-channel mosfets.

        Does anyone have any simpler, more elegant ideas?

Thanks,
Jerome Knapp
